/kloc-How many windows should a 0/0 square balcony open?

Closed balconies are generally divided into main balconies and secondary balconies. The main balcony has a large space, so it is generally more appropriate to open two casement windows. However, if the length of the main balcony is long, you can open three appropriately, similar to the curtain wall casement window, which is also very beautiful. The second balcony is generally short, so it is enough to turn on a fan.
